HOG-SCRAPER.

Specification of Letters Patent.

Patented Nov. 11, 1913.

Application filed August 12, 1913. Serial No. 7 84,383.

To all whom it may concern:

Be it known that we, ANDREW Gr. OLSON and ARTHUR A. BOBERG, citizens ofthe United States, residing at St. Joseph, in the county of Buchanan,State of Missouri, have invented certain new and useful Improvements inHog-Scrapers; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to beaters for hog scraping machines and has foran object to provide a beater that will be yielding in constructionwhereby breakage is prevented.

A further object is to provide a beater that may be constructed at aminimum cost and will be devoid of complicated parts.

With the above objects in View the invention consists of certain noveldetails of construction and combination of parts hereinafter fullydescribed and claimed, it being understood that various modificationsmay be made in the minor details of construction within the scope of theappended claims.

In the accompanying drawing illustrating this invention :-Figure 1 is aplan view of the beater. Fig. 2 is a side elevation. Fig. 3 is alongitudinal sectional view on the line 3-3 Fig. 1. Fig. t is a frontelevation.

Referring now to the drawing in which like characters of referencedesignate similar parts, 10 designates the beater shaft.

In carrying out our invention we provide a heater including a pair ofparallel bars 11 that are connected by cross bars 12 and 13, the latterbeing riveted or otherwise secured in position. Each bar is providedwith an intermediate helical spring section 14, these spring sectionspermitting of the bars yielding in operation so that breakage isprevented. The rear ends of the bars are reduced and formed cylindricalto provide stems 15 which are inserted through suitable Copies of thispatent may be obtained for five cents each, by addressing theWashington, D. C.

openings formed for their reception in the shaft 10, and are secured inplace by lock nuts 16. To the forward connecting bar 13 of the bars aresecured downwardly curving scraper blades 17, such blades being spacedapart and being riveted or otherwise secured in position.

During rotationv of the shaft 10 in the usual manner, the beater will berotated with a resultant scraping of the bristles from the carcass bythe blades 17 while at the same time there will be a yielding of thebars 11 at their intermediate spring portions 14 whereby breakage of thebeater when it impinges against the carcass is prevented.

From the above description it will be seen that we have provided anextremely simple and inexpensive beater that will not become easilybroken, and which is devoid of complicated parts.

What is claimed, is

1.. A beater for hog scraping machines including the combination with abeater shaft, of a pair of parallel bars each having an in termediateportion consisting of a helical spring, a cross bar connecting the outerends of said bar, and scraper blades secured to said crossbar.

2. A beater for hog scraping machines including the combination with abeater shaft, of a pair of parallel bars each having an intermediateportion consisting of a helical spring, cross bars connecting saidparallel bars, stems formed on said parallel bars and engaged throughopenings in said shaft, re-

taining nuts on said stems, and curved scraper blades earned by one ofsand cross bars.

In testimony whereof, we aflix our signatures in the presence of twowitnesses.
